Custom Deal Recommendations by Email using Forms, Bright Data & GPT-4o-mini

This n8n workflow template automates the process of collecting and delivering the "Top Deals of the Day" from MediaMarkt, tailored to user preferences. By combining user-submitted forms, Bright Data web scraping, GPT-4o-mini deal generation, and email delivery, this workflow sends personalized product recommendations straight to a user’s inbox.

⚠️ Note: This workflow uses community nodes (Bright Data and Document Generator) which only work on self-hosted n8n instances.

🚀 What It Does

• Collects user preferences via a form (categories + email)
• Scrapes MediaMarkt’s deals page using Bright Data
• Uses GPT-4o-mini (OpenAI) to recommend top deals
• Generates a structured HTML email using a template
• Sends the personalized deals directly via email

🧩 Community Node Integration

We created and used the following community nodes:

• Bright Data – To scrape MediaMarkt deals using proxy-based scraping
• Document Generator – To generate a templated HTML document from deal data

These nodes are not available in n8n Cloud and require self-hosted n8n.

🛠️ Step-by-Step Setup

1. Install Community Nodes
   Make sure you're on a self-hosted n8n instance. Install:

   • n8n-nodes-brightdata
   • n8n-nodes-document-generator

2. Configure Credentials

   • Bright Data API Key (Proxy + Scraping setup)
   • OpenAI API Key (GPT-4o-mini access)
   • SMTP Credentials for sending emails

3. Customize the Form
   Adapt the form node to collect desired categories and email addresses. Typical categories include appliances, phones, laptops, etc.

4. Design Your HTML Template
   In the Document Generator node, you can tweak the HTML/CSS to change how deals appear in the final email.

5. Test the Workflow
   Submit the form with test data and check that the entire flow—from scraping to email—executes as expected.

5. Data Structuring & Split
   The result is split into individual deal items to be formatted.

6. HTML Document Creation
   Document Generator populates a clean HTML template with the top recommended deals.
